Part 1) Sketch area under standard normal curve over the indicated intervals, and find the specified area.
a) to the left of z=0.15
b) to the right of z=-2.17
c) between z=-1.40 and z=2.03
Part 2) Let z be a random variable with standard normal distribution. Find indicated probability and shade corresponding area under the standard normal curve
Neat, step-by-step solution using graphs is provided.
